Hey
The mcastDropTime attribute controls how long a node waits without a
response from a peer before considering it dead. Careful though, I tried
setting this to be much lower than the default and had all sorts of
problems with nodes adding / disappearing all the time; I wonder what
sorts of values members of this list use as a bare minimum?

In cluster of two nodes, which the parameter that I need to configure
(or to decrease the value) for a node knows immediately that the other
